These are the features that are implemented at the moment:

• Create didimos, supporting different input types, package types, versions and features
• List didimos
• Download didimos, supporting different package types
• Execute on-demand features on didimos
• Supports multiple profiles as an easy way to change between environments or even accounts

Quickstart

1. Install

The CLI is written in Python 3 and is distributed as package on PyPI and can be installed with pip.

pip3 install didimo-cli

If you already have a previous version installed, you should execute:

pip3 install didimo-cli --upgrade

2. Configure with your API Key

Create a new configuration and input your API Key. If you do not have an API Key, please refer to the Getting an API Key section.

didimo init <configuration name>

After setting up the CLI, you can check your account with:

didimo account

3. Create a didimo

Now that the CLI is configured, let's create a didimo based on a photo.

didimo new <path to the photo> photo 

The CLI waits for the didimo to be created and downloads the result in a zip file.

Generating a didimo may include several options, as described on our developer portal.

The tool allows the selection of the avatar structure (--avatar-structure), for which it currently accepts full-body or head-only (default) options. For full-body requests, some extra parameters are available:

• the definition of the body pose (--body-pose);
• the definition of the garments (--garment);
• the definition of a gender (--gender).

Didimo CLI currently accepts the following features (-f):

• oculus_lipsync
• simple_poses
• arkit
• aws_polly

The CLI accepts following output formats (-p):

• glTF
• FBX

In addition to those, it also accepts:

• the definition of a profile (--profile), which will drive the output texture files dimensions and formats;
• the definition of a default hair or baseball cap, from our collection of hairstyles (--hair).

Input type accepts:

• photo
• rgbd (currently only tested with Apple depth images)

Please check all the options and accepted values using the command below.

didimo new --help

4. Generate a package with hairs deformed for the newly generated didimo

Now that we have a didimo package, we may generate a package with Didimo's default set of hairs.

didimo execute hairsdeform <path to the didimo package>

5. Explore

You can list your didimos with:

didimo list

To list the demo didimos use:

didimo list-demo-didimos

For more help, check the documentation on each command with the --help option.

4. Batch processing

The Didimo CLI supports batch processing of photo inputs automatically. Simply provide a path to a directory containing the input files and all files with be processed. Alternatively, you can point to a zip file containing the input files.

didimo new /path_to_batch_input_files photo

Currently, only photo input is supported by batch processing.

This feature will result in standard requests to generate didimos so you should consider bulk processing if you intend to generate a large number of didimos in one pass (please read the following section for more information on bulk processing).

5. Bulk processing

The Didimo CLI supports bulk processing of photo inputs automatically. Simply provide a path to a ZIP file containing the input files and all files will be processed as a bulk request.

didimo bulk new didimos /path_to_batch_input_files photo

An important distinction between batch and bulk processing is that the batch process is controlled by the client application, which makes standard requests to generate didimos, while the bulk request handles the process as a whole. Resulting in a quicker registration of the job but may result on a lower turn-around-time (TAT) as the package is processed in the background, with lower priority. This feature is intended to be used in the generation of a large number of didimos without blocking the user interface.

You can perform queries to assess the status of the processing of bulk requests, using the get command that outputs relevant progress information of each individual item.

didimo bulk get didimos bulk_uuid

You can also query all the existing bulk requests on your account with the list command.

didimo bulk list didimos

Currently, only photo input is supported by bulk processing.

6. Didimo generation templates

The commands related to didimo generation support the use of templates to facilitate the use and prevent unintended errors while generating your didimos. We have predefined templates which are set at system level and you can generate your own.

Use the following command to list available didimo generation templates.

didimo generation-templates list

You can add a new DGT, according to your current DGP signature, using the create command. Use the following command to get instructions on how to use it and see all the available features and options.

didimo generation-templates create -h

You will be able to use these templates as parameter on the commands:

• "new" (to generate a new didimo): e.g. didimo new /path_to_batch_input_files --template templateCodename
• "bulk" (to generate didimos in bulk): e.g. didimo bulk new didimos /path_to_batch_input_files --template templateCodename

You will still be able to override any template values if needed by providing the parameters as you normally would, and the remaining attributes will be fetched from the provided template.

NOTE: These templates need to be created for each DGP (didimo generation pipeline) signature if there are breaking changes to the DGP signature, but are shared across compatible DGP versions.
